Package Integration of a Rotor Position Sensor in a Rotary Transformer

Abstract

A rotary transformer is disclosed herein comprising a stationary portion and a rotating portion. The stationary portion includes a transformer housing, a primary coil positioned within the transformer housing and defining a central axis, and a stationary printed circuit board (PCB). The stationary PCB includes an excitation coil of an inductive position sensor and at least one sensing coil of the inductive position sensor. The rotating portion of the rotary transformer includes a rotating PCB with a secondary coil of the rotary transformer positioned on the rotating PCB. The rotating portion further includes a diode holder connected to the rotating PCB. The diode holder includes at least one target for the inductive position sensor.
